Exterior Envelope & High-Performance Retrofits

We provide exterior envelope upgrades and high-performance retrofits throughout Ithaca, NY and the surrounding areas. This work typically involves removing existing siding, upgrading insulation, improving air and water control layers, and installing new exterior finishes.

A high-performance retrofit focuses on how the house manages air, water, and temperature, not just how it looks from the outside. Done properly, exterior work can reduce drafts, control moisture more effectively, and create a more stable and comfortable indoor environment while improving long-term durability.

Why Exterior Work Requires Care 

Exterior retrofits are more complex than they appear from the outside. Once siding is removed, hidden conditions often come to light, and the way new layers are installed determines how well the house manages water and air over time.

We approach exterior work as a system. Each layer, from structure to insulation to weather protection, needs to be detailed and connected properly. When projects involve specific performance goals or detailed assemblies, we work closely with architects, engineers, and energy performance professionals to ensure those systems are installed correctly.
